As compared to a p-n junction diode(of the same rating), a Schottky diode has
c Explanation: Due to the metal-silicon junction there are no stored charges, hence no reverse recovery time due to which the switching is faster.
c
See lessExplanation: Due to the metal-silicon junction there are no stored charges, hence no
reverse recovery time due to which the switching is faster.
In a Schottky diode, the silcon is usually

Shown below is the diagram of an ideal super diode. When the input voltage Vin is negative, then the output voltage Vout = ?
c Explanation: When the input voltage is negative, there would be a negative voltage on the diode so it works like an open circuit. Hence no current flows through the load and Vout is zero.
